SPECIFICATION forming part of Letters Patent No.394,772, dated December18, 1888.

Application iiled March 26, 1887. Serial No. 232,577. (No model.) i

To all whom it may concern:

Be it known that I, XVALTER S. JARBOE, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State 5 ofPennsylvania, have invented certain new and useful Improvements inPackage-Irapping Machines; and I do hereby declare the following' to bea full, clear, and exact description of the invention, reference being'Io had to the accompanying drawings, which form partof thisspeciiication.

In Letters Patent No. 367,637, gral'ited August 2, 1887, I havedescribed a packagewrapping machine wherein the paper which I5 is toform the wrapper is intermittently fed to a pair of shears, which cutoff a sheet of a size adapted to enfold .the article to be wrapped, thesheet so cut off being' then manipulated and automatically folded overand 2o around and in at the ends of the article being wrapped by meansof certain peculiar mechanism and moving parts operated from a commonshaft.

My present invention has relation to pack- 2 5 age-wrappin g machines,and is designed as an. improvement on the machine described and shown inmy aforesaid application for Letters Patent, and embraces many of theessential features of that application, as well as cer- 3o tain new andnovel features which will be hereinafter fully described and claimed.

In the following description I will refer as briefly as is consistentwith a full and clear understanding of my present invention to the v3 5portion of the apparatus already described and shown in mybefore-mentioned pending application, and will more specificallydescribe those parts which I believe to be new. My present invention hasfor its obj ect the 4o provision of novel means1 for automaticallywrapping packages 0r blocks of solid material in paper or other flexiblematerial.

My invention has for its further object the provision of means forautomatically wrap- 45 ping' articles, packages, or blocks of solidmaterial in a double wrapping of paper or other flexible substance-thatis, two separate sheets or sections of paper or other suitable materialone over the other ata single opera- 5o tion.

My invention has for its still further object the provisions of means ina package-wrapping machine for readily adjusting the machine to wrappackages, blocks, or articles of different sizes.

My invention has for its still further obj ect the provision of novelmeans comprising the peculiar construction, combination, and arrangementof parts hereinafter described for more rapidly, accurately, and neatlyenfold- 6o ing and wrapping packages than has heretofore been possible.

My invention therefore consists in the construction, combination, andarrangement of parts more fully described hereinafter, and 65specifically pointed out in the claims.

Referring to the accompanying drawings, Figure l is a perspective Viewof my improved wrapping-machine; Fig. 2, a side elevation of the same;Fig. 3, a plan view of the same; 7o Fig. 4, a plan view on a largerscale of the framing of the folding devices; Fig. 5, a detail viewshowing one of the movable plates which support the article previouslyto its being wrapped; Figs. 6 and '7, sectional views 75 of thesupporting-plates and their appurtenant parts; Fig. 8, a plan view ofthe sidewing folders; Fig. 9, a plan view of the papersupporting' forksand the device for operating the same; Fig. 10, a side elevation of the8o same; and Fig. Il, a plan view of a portion of the bottom of thetable of the machine, showing the devices for adjusting the sideanglefolders. Fig. 12 is a vertical transverse sectional view on line of Fig.2. Fig. 13 85 is a perspective view of the side-folders and operatingmechanism. Fig. 14 is a vertical longitudinal section, on enlargedscale, of that portion of the machine which embraces the foldingappliances. sectional view, on enlarged scale, of the upper part of themachine on the line z .e of Fig. le. Fig. 16 is a series of viewsrepresenting a package in different stages while being enfolded. 95

A designates the table upon which the working parts of the machine aremounted, and a a a the legs supporting the same.

B designates the main or driving shaft of the machine, suitablyjournaled in bearings roo Fig. l5 is a transverse 9o 71 l), sustained bythe legs a a, and carrying the cam-wheels E Bi, the mutilated gearwheelB2, and the band-wheel B", through which and a crank, Bi", on the end ofthe shaft motion is communicated to the working parts of the machine.

Upon vertical arms c c and horizontal arms c c at one end of the table Aare respectively journaled two rolls or reels of paper or other materialsuitable for enfolding the article to be wrapped, said rolls or reelsbeing lettered C C and sustained on shafts c2 The strips ot' paper orother wrapping material from the rolls C C are designated (7 e, and eachstrip passes through a pair of feedrolls constructed and operating inthe manner ol' the feed-rolls employed for a like purpose in mybefore-mentioned Letters Patentthat is, each pair ot feed-rolls consistsof a large roll intermittently operated by means ol' a dog upon areciprocating` arm taking into teeth upon a wheel Iixed on the shat't ofthe roll, and a spring-stop, el, and a smaller roll mounted in anelastic bearing, thepaper passing between the rolls and being fedpositively but internlittently forward by their motion.

D designates the upper and smaller feeding-roll for the strip (7,journaled in bearings D D', risingl from the table A, the journals oi'said roll being` pressed upon by springs iitted in sockets 7 (7', and Dldesignates the lower feed-roll mounted on a shaft, d2, that is journaledin hangers 73 (7ii on the bottom oi' the table A. The shat't d2 projectsbeyond the hanger on one side, and to the projecting end of the shaft issecured a wheel, D, having teeth t7 d" d" t7", with which engagesaspringdog, (75, on an arm, (7, loosely mounted on the shaft. The end olthe arm 7 is pivotall y attached to the lower end of a vertical rod,(7T, which is pivotally attached at or about its middle to a curvedpitman-rod, 17S, connected at its other end to the crank B on the endot' the main driving-shaft B.

B designates the larger feeding-roll for the strip e, mounted on ashalft, e2, journaled in standards E E', and having a wheel, Ewith teethel er1 e c", a pivoted arm, e", carrying a dog, c, and pivotally securedto the end of the vertical rod (77.

E2 designates the smaller [feed-roll ol' strip e, journaled in thestandards E E and sustained on springs in sockets e e. The l'ecdroll l)2of the strip (7 is, it will be observed, somewhat larger than thefeed-roll E of strip e, and by reason of this dillerenee in the size ot'these rolls the strip t7 will be li'ed :forward a somewhat greater'distance than the strip c at each downward movement ol' the vertical rod(77.

The several rolls I) E D2 E2 are grooved, and guiding-wires f f f f onframes F and l1v project through the grooves and serve to guide thestrips (7 and c to the cutting-shears.

G designates the stationary blade ot' the shears, tixed on a standard,G', and G2 designates thel movable blade of the same, which is fixed ona rock-shaft, G3, that is journaled. in the standard G and in astandard, Gl. A ever, G5, is secured to the rock-shaft G near thestandard Gl, and through said lever the rock-shaft receives motion froma verticallymoving' portion oli' the folding devices.

llaving thus briefly described the device for feeding the wrappingmaterial, I will now describe thc frat 11e-work of the wrappin devicesand the manner in which the same may he adjusted to accommodate articlesor packages of different size, and will then describe the moving partsof the wrapping devices.

ll ll ll lll ll2 ll2 designate six posts or pillars rising from thetable A and joined together by cross-pieces 7ly 7i 712. Upon top oi' thecross-pieces 7e 7L 7l2 are laid two T-irons, l I, which extend from theshears to near the end otl the table A. These two irons are secured upontop of the cross-pieces by means ot' laterally-projecting tlat strips fi'11, having slots 'i' t near their ends, through which pass screws 172i2, that rise from the standards l-I H and lil H, fitted with thumb-nuts"3 fi, By means otl the slotted strips 'l'. 'i and the thumbnuts 'iii lthe distance apart of the irons I l may be readily adjusted and fixed,and, as these irons support and carry the adjustable portions ot' theframe-work of the wrapping devices, the whole adjustment of the trame isaccomplished by loosening the thumb-nuts alulmoving the irons I ltogether or apart. From each of the irons I l', near the rear end ot'the same, depend two vertical posts, K K K K, and to the insides otthese posts are secured two metallic plates, K K whose forward ends arespirally curved, the (mrvature ot' the ends serving, as will presentlyappear, to lorm the last Iold ot the wrzLpping material upon the articleorpackage, and the straight portions ot' these plates Yform the sides olthe chute or passage through which the wrapped articles are deliveredfrom the machine.

K2 (lesignates a wide Ilat plate fixed horizontally between the verticalplates K K and forming a part of the top ol' d elivery-cluite abovere'lerred to. The plate K2 has a wide upturned end, K3, the lower edgeot' said plate being roumled oil, as shown, and this upturned end servesas a shield and stationary folder, aetil'lg to li'old down thehorizontal flap oi' the wrapper as the article is pushed under saidplate. To the plate K2 are secured two cross-hars, 7x5" 7.9i, slottednear their ends and having uprights Kl K", which V(it into tubularsockets 7s." 7.1i on the under side ot the crosspieces 7L 71.. Spiralsprings may be arranged within the tubular sockets 71'." 71:", and thesaid sockets and spiral springs serve to guide and sustain the top oi'the delivery-chute and permit the same to give il' any ot' the articlespassing theretllrough should be thicker than the others. secured. byscrews L15 7u, passing thrmigh the slots `in said cross-bars, twoplates, lx 7n, which.

IOO

IIO

To the said cross-bars 7.;3 7;." are extend from just in the rear of theupturned end of the plate K2 to the rear end of the same. Upon top ofthe plates le 7c are pins k7 k7, which pass through holesin lateral armskg ks on the standards or posts K K K K.

Upon a line with the curved ends of the vertical side plates, K K', andafiixed to the edges of the plates 7e k, are two vertical ears, k2 k2,having' their forward ends curved outwardly and their lower forwardcorners turned up sli ;htly,l said ears acting to turn in the last anglefold of the wrapping' material, as shown at 4, Fig'. I6.

The framework of the wrapping' devices above described is capable ofbeing' adjusted to accommodate differentsized articles or packages, asfollows: The thumb-nuts 'i3 'i3 and the screws 7J being' loosened, theirons I I may be set farther apart or closer together in their movement,carrying with them the vertical side plates, K K, and the plates k k,thus increasing or diminishing' the width of the delivery-chuteaccordingly as said irons are moved closer together or farther apart.The web of the irons I I is turned in near the forward end of the same,and upon the outside of the web on each side is secured a block ofmetal, L, which is substantially triangular in cross-section. Upon topof t-he block L is secured an arm, Z, which projects upward andoutwardly, and to said arm is attached a spring', Z2, to the other endof which is secured a plate of metal, Z3, that passes through a slot,Z4, in the web of iron I. A pin, Z5, is fixed in the slanting undei'side of the block 'Ii, and in one position of the plate Z3, as in Fig.(i, its outer edge bears against the said pin. The plate Z3 has a pin,16,011 its bot-tom, that passes through a triangular or wedge-shapedslot, on, in the head fm of a sliding plate, M. This plate M lies andslides upon the outside of the iron I, and is held in position by ascrew, m2, that passes into the web of the iron and through a slot, m3,in a vertical liange, m, near the end of the plate. Upon top of theflange mt and at each end of the same is a lug', m5 m5, and across-head, N, upon a horizontal]y-reciprocating rod, N', contacts withthese lug's alternately, thus imparting an intermittent reciprocatingmotion to the side plates on each side. The plate Z"g has a certainamount of lateral playin the slotZ", and is capable of turning on theedge of said slot as on a pivot when its inner and lower edge is pressedupwardly, and by this movement the plate is disengaged from the pin l,and when so disengaged the spring Z2 draws the plate back until itsinner edge is just on a line with the inner edge of the slot Z4.

The two positions of the plates Z3 Z3 are best seen in the detail views,G and 7, and the manner in which the same are operated is as follows:The plates l"E Z3, being in the position shown in Fig. U, receive andsustain the package to be wrapped until such time as a table, T, whichrises up under the plates l Z3 at certain regular intervals, contactswith said pl ates and lifts their inner ec ges.

This causes the plates to become disengaged from the pins Z2, and theytly'back into the position shown in Fig. '7, thus allowing the articleto rest upon the wrapping material, which projects over said table. Thetable T and the plates Z3 Z3 are restored to their former position bythe backward motion of the slide-plates M, the triangular slots n1acting' upon the pins l and forcing' the plates out through the slotsand until their rear edges again engage with the pins Z5 Z5.

O designates. a tiat horizontal apron which is placed in the rear of thepivoted plates Z3 Z3, and is secured to the inner edge ofthe T-iron onone side, projecting' through an opening in the web of the iron on theother side and beneath the bottom of the chute P.

P designates a second table which rests upon the cross-pieces 7L h2, andhas a central rectangular cavity, p, that lies under ends of the irons II. This table P serves to receive and sustain the wrapping material asit is fed forward from the rolls, and at the side of the cavity p arearranged adjustable guides p p', which hold the paper in position overthe cavity p while the table is ascending'.

In order to prevent the paper or other wrapping n'laterial 'fromsagging' down into the opening p in the table P, I provide two wireforks, p2 p2, which ext-end over said opening while the paper being' fedforward, and which are turned out of the way by appropriatc mechanismwhen the paper is in proper position. These wire forks are fast to thetops of uprig'ht rods P3233, which are swiveled in the blockp, to whichis hinged the first of the hinged plates g, which effect the folding ofthe first flap of the wrappingmaterial over the top of the article.These rods p3 p3 are square in cross-section, and are each given aquarter-turn, so that they form spirals, and they pass through squareholes in arms 195195, projecting' from a cross-bai', p6, which issecured to the tops of vertically-reciprocating rods which carry theracks operating the folder Q, the result of which arrangement is thatupon the downward movement of the cross-bar p the wire forks p2 p2 areturned aside from over the opening p, and upon the upward movement ofthe same the wires are restored to their original position.

One of the features of the present device to which I will here callparticular attention is that the weight of the article to be wrapped isutilized to effect a portion of folding of the wrapper, and this iseffected by having the article descend through the opening p in theplate P, taking down with it the two sheets of wrapping material whichhave been previously cut from the strips CZ and e and folding up thesides of the same against the sides of said openin The table T, whichhas been previously referred to and described as ascending beneath theplates l3 Z3, and after operating the same receiving' the article to bewrapped and the wrapping material, con- IOO IIO

sists of a fiat plate mounted upon a vertical post or standard, t,thatis connected by a pitman, t', with the gear-wheel t2, which receivesmotion from the mutilated gear B2 on the main shaft B, the table beingthus operated by the same mechanism which in the machine described in mybefore-mentioned patent operated the tilting-trough and its lgilunger.

It being premised that the folding devices are substz'mtially the sameas those described in my aforesaid patent, it will be unnecessary toparticularly describe the same; but I will now describe the meanswhereby said folding devices may be adj usted to operate upon paclc agesof di llerent sizes.

It will be seen that what I call the endwing folders,7 which are markedR R in the drawings, are hinged to a skeleton frame composed of thecross-bars R2 R:E and vertical rods R* R", which reciprocate throughholes in the table, the cross-bar R carrying an anti-friction roller,w", which travels in a cam-groove, SS, in the wheel B. Another andsimilar frame composed of vertical posts s2 s2 and cross-bar U, thelatter carrying a roller, c5, which engages with a cam-groove, In, inthe wheel B', is provided at its upper end with the vertical racks s s,which engage with toothed segments S S, fixed to the pintles of thefolding wings R R, which latter are operated by the engagement and(Ko-operation of the racks and segments, while the frames are operatedin a di tferential manner under con# ditions and for the purposedesignated in my patent already referred to. The rock-shaft G3, whichactuates the shears, receives motion from the frame R2 R3 through avertical rod, g5, connected to the bar R2.

In Fig. S of the drawings I have lillustrated the end-ning folders andthe means for adjusting the same. The said end-wing folders, which arelettered R R, are hinged to sliding blocks 'i' fr, dovetailed into slotsin the plate r and having on top and at their inner ends lugs i r?. Theplat e fr is lformed with a piece, "r3, which is in line with the lugs'12 i, and the lugs r2 fr? are formed with reverse screw-threads, so asto receive a right and left screw, yrl, which passes through them andthrough the piece r3. The screw tu rnsin the piece l without traveling,and a jam-screw,

fr, serves to fasten the screw r3 when the proper adjustment has beensecured. As the toothed sections S, by means of which the plates R R areturned, are fast on the pintle ot' said plates, it is necessary toprovide for the difference in position of the same, and accordingly Imount the racks s s, with which the sections engage, upon arms s s',which pass through slots Vin the head of the verticallymovable rods s2,through which said racks receive motion from the cam-wheel land securethe arms in the slots by means of keys .ST si, as shown.

The horizontally-swinging side-angle folders are constructed and operatesubstantially in the manner shown and described in my previousapplication, but are made adjustable by the following arrangement ofdevices:

The folders consist of the horizontallyswinging arms I NV, which aresecured at their outer ends to short vertical shafts a n, which passthrough slots d5 a in table A and are journaled in blocks n a, whichmove in dovetailed grooves in the table, the said blocks beingadjustable toward and from the edge of the table by screws n2 n2. To thelower ends of the shafts 'nu are secured arms n.3 n3, which havefriction-rollers a4 a4, that work in slots n of in a frame, XV', whichis mounted on a l1orizontally-reciproeating rod, It, which receivesmotion from the cam on the periphery of the wheel B. The rod I2 isutilized for the purpose of giving motion to the rod N, which carriesthe cross-head and the plunger N2, proj eeting out beyond the end of thetable A and cormected to said rod by a frame, IW. Operation The articleto be wrapped (which is, for instance, a cake of soap) is fed to thetable O by the chute P', and is slid forward upon the supporting-platesZ3 Z3 by the plunger N2. At the same time the two strips d e have beenfed forward (the lower strip a somewhat greater distance than the other) below the cake of soap, a proper length being cut off by the shears.The forks p2 p2 have been utilized to sustain and guide the wrappingmaterial, and are now turned aside out of the way. The table T, arising,releases the plates Z3 Z3, and the soap and the wrapping materialdescend and rest upon the table T. The latter now descends, and the twosides of the wrapper are 'folded up into vertical position, seen at Fig.lo, by contzlcting with the sides of the opening p in table I). Thetable T continues its descent until its surface level with the surfaceof table A. The folder Q now comes into play and folds down the wrappingmaterial at one side, as seen at 2, Fig. l ti. A plunger, V, thatreceives motion by means of V fromv the cam upon the periphery ofcam-wheel B2, now pushes the article along beneath the end ot' plate K2,and the wrappin material on the other side of the soap is thereby foldeddown over the top. The en d-wing folders now come into play, and thepackage assumes the shape shown at 3, Fig. 1G, and then the movableside-angle folders IV i, the package then appearing as at et, Fig. lo.The article is then pushed still farther under the plate K2 bytheplunger V, andthe stationary sideangle folders give it the shape shownat 5, Fig. 1G, and the curved ends ot' the vertical plates K* K completethe folding operation. The parts now return to their former position,and the next article is operated upon in like manner.

The manner of adjusting the several parts of the machine has beenhereinbefore sufieiently described and need not be repeated.

Having describedmy invention, I claiml In a package-wrapping machin eprovided with a paper-cutting instrument, substantially as described,and a series of paper-folding wings, the combination, with saidcutting-im IOO IIO
